Problems solved by technology

However, single-junction thin-film photovoltaic modules have limitations in their performance, so double-junction thin-film photovoltaic modules or triple-junction thin-film photovoltaic modules formed by laminating multiple unit cells have been developed in pursuit of highly stabilized efficiency (stabilized efficiency)

Abstract

The invention relates to a series integrated photoelectric module, comprising a lower electrode formed by laminating on a substrate, a photoelectric conversion layer, and first and second batteries of an upper electrode. The photoelectric conversion layer comprises a first unit battery layer, a second unit battery layer, and a middle reflection film disposed between the first and second unit battery layers. The lower electrode of the first battery and the lower electrode of the second battery are isolated by a lower electrode isolating groove. The photoelectric conversion layers on the lower electrode of the first battery are isolated from each other, forming a plurality of through holes for connecting the upper electrode of the second battery and the lower electrode of the first battery.

Description

technical field [0001] The invention relates to a serial integrated photoelectric module and a manufacturing method thereof. Background technique [0002] At present, with the prediction that existing energy sources such as oil and coal will be exhausted, people are paying more and more attention to alternative energy sources to replace these existing energy sources. Among them, solar energy has attracted special attention because of its abundant resources and non-polluting environment. [0003] Like diodes, photovoltaic modules that convert solar energy into electricity have a junction structure of p-type semiconductors and n-type semiconductors. When light hits the photoelectric module, there is an interaction between the light and the material that constitutes the semiconductor in the photoelectric module, generating electrons with (-) charges and holes with (+) charges, and the flow of charges generates current. [0004] Photoelectric modules are divided into bulk type...
